A carnot engine, whose efficiency is 40 % takes heat from a source maintained at temperature 600 K . It is desired to have an efficiency 60 % , then the intake temperature for the same exhaust (sink) temperature should be
Options
- A1800 K
- B1200 K
- C900 K
- D600 K
Correct answer
C. 900 K
Step-by-step solution
For Carnot's engine, aligned & =1- T_L T_H & 40 100 =1- T_L 600 & T_L 600 = 60 100 & T_L=360 ~K & Now, 60 100 =1- 360 T_H & 360 T_H = 40 100 T_H=900 ~K aligned
